I have norton 360 antivirus + malwarebytes premium subscription. Both of them cannot find anything. Even in safe mode. But from time to time happens something like redirection to some kind of suspicious sites with content that "You won something blah blah blah". The funny thing is that virus not in the browsers. Because it happened even in Steam window/browser(steampowered.com). So doesn't matter the browser, Chrome, Firefox, Steam it just happens where is web content in the window. I made a screenshot here to illustrate how it looks like with steam.
